STOCKTON, Calif. — An hour before she was killed by a hit-and-run driver, Trinidad Cornelio of Stockton spoke to her granddaughter Gisela Flores, congratulating her for passing her driver's test.

"She was the only reason I did things, because she encouraged me a lot," Flores told ABC10. "She always encouraged me to do better and reach my goals. She was my motivator."

Last year, on Dec. 12, Cornelio was walking across the street to attend mass at Presentation Church on Benjamin Holt Drive near Leesburg Place.

That's when she was hit by a pickup truck. The 71-year-old grandmother, mother and wife died at the scene.

The driver of the pick-up didn't stop. Because of that, no other description of the vehicle has been released by the California Highway Patrol.

"She was always there for my family whenever we needed her," said Cornelio's grandson Vincent Acalos. "Like, she even took my family in at one time to live with her."

Avalos says the last time he saw her was two weeks before she died. His family was invited to her home for dinner.

"I pray every night that they'll come forward," Avalos said. "[I] pray to God saying, like, 'please just bring justice to my grandma,'" Avalos said.

So far, no one has come forward, and state police have no leads on identifying the driver of the pickup truck.

The family hopes by keeping her memory alive before the public, someone who knows something will finally give investigators the tip they need to make an arrest.

"If this was your grandma, you would want justice also," Flores asked.
